摘要 |
<p>A method for the preparation of a flexible foam, an integral skin foam or a microcellular elastomer by reacting an organic polyisocyanate and an isocyanate-reactive composition comprising at least one isocyanate-reactive compound of molecular weight of 1000 to 10000 and a functionality of 2 to 4 in the presence of a blowing agent, characterised in that the reaction is conducted in the presence of an inert, insoluble, organic liquid which has a boiling point of at least 60 DEG C at 1 bar. CFC-free foams and elastomers of good quality are obtainable.</p> |
